Comment 2 for bug 1306491

Hello,

Do I need to reboot the node after the modification in nailgun agent?

Objet : [Bug 1306491] Re: no disk information leading to error during node allocation

Hello,

The problem is that the disks are detected as external (in ServeRaid
controllers) and nailgun agent doesn't see them.

Workaround in Fuel 4.1:

ssh to the node:
vi /opt/nailgun/bin/agent
in REMOVABLE_VENDORS add "ServeRA",
exit

You need to do two times, one during bootstrap and another one after the
operating system installation.

Title:
  no disk information leading to error during node allocation

Status in Fuel: OpenStack installer that works:
  New

Bug description:
  Hello,

  We are trying to create a HA environment with ubuntu release.
  the architecture of the plateform is :
  3 servers IBM System x3550 -[7978B9G]-
  1 server IBM System x3550 M3 -[7944W6B]-
  4 HP Proliant BL680c G5

  each server has the same network configuration :
  eth0 trunked : public and admin
  eth1 not trunked : pxe
  eth2 trunked : storage network

  during the nodes discovery, it seems there is a problem with the 3 servers IBM System x3550 -[7978B9G]-
  they are seen with no disk : Disks 0 drives, 0 bytes total

  where as when connecting on the node with ssh from the fuel master node we've got the following result for 'fdisk -l' command:
  Disk /dev/sda: 73.3 GB, 73283928064 bytes
  255 heads, 63 sectors/track, 8909 cylinders
  Units = cylinders of 16065 * 512 = 8225280 bytes
  Sector size (logical/physical): 512 bytes / 512 bytes
  I/O size (minimum/optimal): 512 bytes / 512 bytes
  Disk identifier: 0x0009ea9c

     Device Boot Start End Blocks Id System
  /dev/sda1 * 1 3891 31249408 83 Linux
  /dev/sda2 7083 8910 14678017 5 Extended
  /dev/sda3 3891 7083 25636863 8e Linux LVM
  Partition 3 does not end on cylinder boundary.
  /dev/sda5 7083 8910 14678016 82 Linux swap / Solaris

  Partition table entries are not in disk order

  So there is a disk on the server

  So when we try to add them to the environnement we've got the following error
